Oil Analysis

Term from Mechanical Maintenance industry explained for recruiters

Oil Analysis is a preventive maintenance technique where oil samples from machinery are tested to check the health of equipment. It's like a blood test for machines - by examining the oil, maintenance teams can spot potential problems before they cause breakdowns. This helps companies save money by preventing unexpected equipment failures and planning repairs at convenient times. The process involves taking oil samples from engines, gearboxes, or other mechanical equipment and sending them to specialized laboratories for testing. This is a key skill in predictive maintenance and reliability programs.
